"Amy's spinal cord was completely severed at the T11 vertebrae, but, miraculously, a broken vertebrae stopped within millimeters of rupturing her aorta, and she did not suffer any head trauma," the letter continued.

"Amy awoke within hours of surgery acting like her typical spunky, boisterous, ebullient self and has spent the last 24 hours entertaining her family and her medical staff in the ICU. She has made at least one male nurse blush. Amy's attitude has been overwhelmingly positive and optimistic. She has been far more of a comfort to us than we have been to her."

Her family continued, "She is a fighter. With the unconditional love and support of her friends, family and fans, Amy welcomes the challenges she will face as she opens this new chapter of her life."
